A Universally Composable Framework for the Analysis of Browser-Based Security Protocols

摘要

Browser-based security protocols perform cryptographic tasks within the constraints of commodity browsers. They are the bearer protocols for many security critical applications on the Internet. Roughly speaking, they are the offspring of key exchange and secure sessions protocols. Although browser-based protocols are widely deployed, their security has not been formally proved. We provide a security model for the analysis of browser-based protocols based on the Universal Composability framework.
